IPC: C22C38/34
Filed: 1970-07-16
Abstract: 1306260 Alloy steel razor blades SANDVIK AB 16 July 1970 [23 July 1969] 34580/70 Heading C7A A razor blade is formed from an alloy steel comprising the balance, apart from impurities, being Fe. The steel strip may be heated at 850‹-1000‹C, quenching (preferably to below 0‹C.), optionally tempered at 100‹-250‹C. and then formed into a blade by grinding. The final body may then be tempered at 250‹-450‹C. (e. g. during application of a polymeric coating). The corrosion resistance of the blades may be enhanced by vacuum deposition of a Cr coating, at least on the cutting edge, prior to the polymeric coating.
Patent GB-628402-A (GB)
Title: Improvements in switches for use in telephone or like systems
IPC: H01H67/26
Filed: 1946-11-21
Abstract: 628,402. Automatic exchange switches. AUTOMATIC ELECTRIC LABORATORIES, Inc. Nov. 21, 1946, No. 34588. Convention date, Nov. 21, 1945. [Class 40 (iv)] In a switch of the type having a plurality of contact sets arranged in ranks and files, a single set of magnets in conjunction with a common control magnet serves for the selection of the appropriate rank and file. For each contact set 23, 24 there is provided an operating member 43, and ten such members are supported on the lips 21 of each rank selecting bar 41. When a rank selecting bar is turned slightly clockwise, the contact operating members drop and engage slots in the ten file selecting bars 7, so that movement of a selected one of these bars to the right shifts the corresponding operating member to close the required contact set. Each selecting magnet 2 has an L-shaped armature 37 provided with an end extension 4 for choosing a rank selecting bar and a downward extension 6 which engages a slot in the corresponding file selecting bar 7, the extensions 6 of the several armatures being staggered. The first magnet 2 to be energized turns its armature anti-clockwise and the extension 4 depresses the corresponding one of ten spring fingers 15 carried by a bar 14, so that upon longitudinal movement of this bar by the energization of the common control magnet 16 the lower end 39 of the finger 15 engages an extension 40 of the corresponding rank selecting bar 41 and turns it clockwise, allowing its contact-operating members 43 to drop, this condition being maintained after the release of the magnet 2. The energization of a second selecting magnet moves the corresponding file selecting bar 7 to the right by means of the extension 6 of its armature and thereby shifts the corresponding one of the contact operating members prepared by the previous selecting operation. The movement of the bar 14 allows a spring pawl 32 at its end to engage a cam 27, so that when the magnet 16 releases, the return of the bar 14 by spring action rotates the cam and brings a latch 28 into engagement with a lug 34 on the displaced file selecting bar 7. The connection therefore remains held until a magnet 35 releases the pawl 32. It may be noted that the first selecting magnet also moves a file selecting bar, but without effect, as no latching takes place until the control magnet 16 releases. The selecting magnet armatures also have end extensions 5 for controlling auxiliary contact sets. For use in telephone switching, a number of the switches shown in Fig. 1 are mounted one above another, with the passive contacts 24 formed by bare wire multiples.

Title: Improvements in or relating to the plastication of cellulose esters or ethers
IPC: C08K5/00
Filed: 1933-04-13
Abstract: Moulding-powders are made by agitating a cellulose ester or ether and a plasticizer in suspension in an aqueous medium in the presence of a water-soluble swelling agent for the cellulose derivative, said swelling agent having a boiling point not substantially above 170 DEG C.  Suitable swelling agents are alcohols and ketones such as acetone, cyclohexanol, and cyclohexanone. Preferably, the cellulose derivative is treated in finely divided form obtained by grinding or precipitation, and the amount of aqueous medium is large, e.g. of the order of 4--25 times the weight of the cellulose derivative.  In a modification, the cellulose derivative is dissolved in a solvent, for example, acetone, and water is added until incipient precipitation takes place, whereupon the solvent is evaporated until the liquid has little or no solvent action for either the cellulose derivative or the plasticizer.  The plasticizer is then added and the whole stirred.  If the plasticizer is solid it may be added in molten condition.  In all cases the mixture is agitated for some time, e.g. for 20 minutes to one hour, preferably at a temperature of 35 to 100 DEG  C.  Additions may be made of other substances such as natural or synthetic resins, stabilizers, dyes, lakes, pigments, filling substances such as silica gel and wood flour, and substances reducing inflammability.  The product may be moulded into sheets, slabs, rods, tubes, or other articles.  Specification 319,073, [Class 2 (ii)], is referred to.ALSO:Moulding-powders are made by agitating a cellulose ester or ether and a plasticizer in suspension in an aqueous medium in the presence of a water-soluble swelling agent for the cellulose derivative, said swelling agent having a boiling point not substantially above 170 DEG  C.

Title: Travelling wave tube
IPC: H01J23/11
Filed: 1954-12-07
Abstract: 769,724. Travelling-wave tubes. RADIO CORPORATION OF AMERICA. Dec. 7, 1954 [Jan. 4, 1954], No. 35454/54. Class 39(1). In a travelling-wave tube, the coupling of the wave to the beam is arranged to be, at least over the initial modulating section, relatively low at a noise current maximum of the noise standing wave occurring along the beam and relatively high at a noise current minimum ; the overall noise factor is decreased. The coupling may be varied by varying the beam diameter. In Fig. 3, the gun 5 produces a beam that is initially divergent at the cathode and is periodically focussed and defocussed in the strong axial field produced by electromagnet 7. A transition magnet 8 may be provided between the magnet 7 and a relatively weak focusing magnet 9. In Fig. 4, groups of discs 31 at different potentials provide electrostatic focusing and defocusing fields. Beyond these groups the discs may be at uniform potential and a focusing electromagnet provided, or the discs may be divided into insulated groups of smaller axial length to provide electrostatic focusing with shorter focal length and smaller variations in beam diameter. The coupling may be varied by varying the diameter of the wave structure. In Fig. 5, the helix 55 is supported by insulating strips 57. In Fig. 7, a helix 61 of uniform diameter supports coupling rings 63 which have apertures of varying diameter. A disc-on-rod wave structure surrounded by a hollow beam or a baffle loaded waveguide may be used. The coupling between the beam and the wave may be discontinuous. In Fig. 9, resonators 67 coupled to a delay line 73 modulate the beam at discrete points only. In between, the beam is shielded from the fields by tubes 77. The coupling may also be varied by using a pair of coupled helices 78, 79, Fig. 10, as the wave structure. The outer helix may terminate beyond section A or increase in pitch. The noise standing wave may be determined by analysis or by probe measurements.
